Application filed March 16, 1911. Serial No. 614,801.

improvements in locks adapted particularly for use in connection with swinging doors.

The invention embodies particularly a slmple form of lock casing carrylng a piv- 4 oted hasp plate adapted to be engaged with a keeper carried by the frame of the door by proper movement of the plate, locking mechanism being associated with the plate for controlling its operation in the practical em ployment of the invention.

For a full understanding of the present invention, reference is to be had to the fol lowing description and to the accompanying drawings, in which- Figure 1 is a horizontal sectional view showing a door and frame partially, and the invention being applied thereto, dotted lines illustrating the movement of the hasp plate in being disengaged from the door; Fig. 2 is a front elevation of the locking casing and interior mechanism, the hasp plate being in open position, and certain parts being shown in section; Fig. 3 is a transverse sectional view on the line 3-3 of Fig.2; Fig. 1 is a longitudinal sectional view on theline 4-4 of Fig. 5; F ig. 5 is a front elevation of the lock; Fig. 6 is a detail perspective view of the sliding bolt; Fig. 7 is a perspective View of the keeper; F 1g. 8 is a fragmentary sectional view showing amodified form of keeper.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

In the drawings, 1 denotes the door and 2 the frame in which it is mounted. The lock casing is shown at 3 and is screwed or otherwise fastened on the door at the free or swinging portion of the latter. Attached to the frame 2 is a keeper shown more clearly in Fig. 7 and which, for purposes of strength may be constructed of angular form, as shown in Fig. 8. The casing 3 has a base plate 3, and also a covering plate 3 spaced from the base plate so that a certain portion of the interior of the casing is housed to receive locking mechanism comprising the sliding bolt 5,'the latter being of somewhat peculiar formation. The bolt 5 consists of inner and outer spaced parts 5 "and 5", respectively, the former being adapted to slide against the base plate 3 while the latter constitutes a locking member cooperating with the hasp plate 6 which is pivoted between its ends as shown at 7 to one end portion of. the casing 3. The end port-ion of the hasp plate 6 adjacent to the pivot 7 has a hook 8 adapted to engage in the opening of the keeper 4, and the opposite end portion of the plate 6 carries the rotatable handle 9 which passes through the plate and has on its inner end a catch 10, movable into and out of engagement with a notch 11 in the casing. The outer locking member 5 of the bolt 5 has an inwardly extending flange 12 extending therefrom to engage with a guide flange 13 extending longitudinally of the casing 3 and projecting outwardly from the base portion 3 of the latter. is limited by means of projections 13 on the member 3, and is efl'ected by means of a key actuated member 14, the latter having a toothed segment 15 normally engaging a toothed rack 16 formed on one edge of the portion 5 of the bolt 5. The key actuated member 14 is provided with notches 17 in its outer side to receive corresponding projections of a key 18 adapted to be introduced into the casing through a suitable key-hole 19 in the hasp plate 6. Projecting from that portion of the member 14 opposite the segment 15 are lugs 20 against which a spring 21 is adapted to bear, cooperation of the parts 20 and 21 being such that the spring will tend to hold the sliding bolt at one or the other of its limit-s of movements. The locking member 5 of the bolt 5 .is adapted to engage a keeper 22 projecting inwardly from the hasp plate 6, whereby the latter may be locked in closed position with respect to the casing, as shown most clearly The sliding movement of the bolt 5 9, disengaging the catch 10 from the notch 11 and then swings the hasp plate outwardly into the dotted line position shown in Fig. 1, thus disengaging the hook 8 from the keeper 4 on the door frame, permitting bodily movement of the door. In closing the door, the operation above described is reversed. In order to lock the door from unauthorized opening, the key 18 may be introduced for cooperation with the key actuated member 14, and by turning the latter, the bolt 5 will slide into engagement with the keeper 22 to positively lock the hasp plate from outward movement necessary to disengage the same from the keeper 4.

Having thus described my invention, What I claim as new is:

1. In a lock, the combination of a casing, a hasp plate pivoted thereto and having an engaging hook for cooperation with a suitable keeper, a locking bolt mounted in the casing, a keeper projecting from the hasp plate for engagement with the locking bolt, a handle for manipulation of the hasp plate, and a catch operable by the handle for temporarily holding the hasp plate in a predetermined position.

2. In a lock, the combination of a casing,

the hasp plate, and locking means in the casing comprising a sliding bolt composed of an outer locking member and an inner member, the latter having a rack formed thereon, and the locking member being arranged to coact with said keeper, and a key actuated member in the casing having a segment meshing with the rack aforesaid.

3. In a lock, the combination of a casing, a hasp plate pivoted thereto and adapted to close the outer portion of the casing, a handle for manipulating said plate, a keeper projecting inwardly from said plate into the casing, a locking bolt coacting with said keeper and consisting of a locking member, and an inner member spaced therefrom, a key actuated member cooperating with the inner member of the locking bolt to move the latter, a flange projecting from the locking member, and a guide flange projecting from the casing and cooperating with the flange first mentioned to direct the movement of the bolt.

In testimony whereof I aflix my signature in presence of two witnesses.
